PLEASE READ THE FOLLOWING INSTRUCTION
CAREFULLY IN ORDER TO MAKE SURE THAT THE
HEATER IS USED PROPERLY AND DOES NOT CAUSE
MALFUNCTION.
1. USE
Universal oil heater are suitable for heating big size buildings
without central heating (shops, service stations, industrial build-
ings, warehouses, inventory buildings, basements, garages,
etc.) The heater runs on most oils of mineral and plant origin,
such as motor oils, heating oil, gear oils, hydraulic oils at a tem-
perature of 15ºC and maximum ignition temperature not lower
than 56ºC and density above 980 kg/m³.
NOT TO BE USED WITH TRANSFORMER (INSU-
LATING) OILS. THEY MAY CONTAIN SUBSTANCES
THAT CAN DAMAGE THE HEATER.
2. STORAGE CONDITIONS
Universal oil heaters should be stored in the following condi-
tions:
temperature -20 - +85°C
relative humidity 5-85%
pressure 800-1200hPa
free of dust
free of chemical pollutants
3. CONDITIONS FOR USE
Universal oil heaters should be operated under the following
conditions:
temperature 0 - 30°C
relative humidity 5-85%
pressure 800-1200hPa
environmental impact protection IP21
appropriate ventilation of heated area
4. CHARACTERISTICS OF THE CONTROL PAN-
EL
the heater may be regulated and set at 17 and 33 kW,
protection against overheating the burner,
protection against overow of oil in the burner,
automatic retaining of previous settings in case of power
failure.
5. SAFETY MEASURES
Universal oil heater is connected to 230V/50Hz alternating
current network.
Universal oil heater is equipped with two bimetallic sensors
assuring safe and effective functioning of the device.
Bimetallic sensor (FIG4/p1) in the burner triggers reaction in
form of clenching contacts when the temperature in burner rises
above 40°C and opening of contacts when the temperature falls
below 35°C.
Second bimetallic sensor (FIG4/p2) is installed next to the
blower fan with threshold temperature set at 90°C. Clenching of
contacts, when threshold temperature is exceeded, causes that
the burner immediately switches into the overheating mode (see
point. 8 of the instruction).
The heater is also equipped with weigh sensor placed under
the overow tank (the so-called overow fuse) (FIG4/p3).
When the tank is lled, the heater immediately switches into
the overow mode (see point 8 of the instruction).
The control panel of the heater is factory - connected with
other elements of the system (such as sensors, pump, and fan)
and it is a safety requirement that during regular use there be no
interference with covered and sealed part of the control panel
as well as integrity of wiring. Any interference of unauthorized
person may cause an electric shock (230V/50Hz) and burns.

7. INSTALLATION
When installing the heater, all local regulations are to be com-
plied with, including regulations referring to national norms.
Place the heater on at surface made of concrete.
Level the device in order to check if the heater is levelled
correctly, place the vaporising pan in the lower part of the
combustion chamber and pour a small amount (approximately
250ml) of diesel oil onto it. The oil should stay exactly in the
middle of the pan.
Install current stabilizer (valve) on the combustion cham-
ber’s outlet pipe in order to maintain constant draught inside the
pipe during the operation.
Install at least 5 meters long, smooth and temperature re-
sistant horizontal ue (not aluminium ue) in order to provide
optimum draught.
Check tightness of all joints, if necessary use the insulation
tape.
Make sure that the vaporising pan is placed centrally in the
combustion chamber (FIG5/p3).
Place the upper ring inside the combustion chamber with
ange facing upwards and install the hot air pipe (FIG5/p2).

Check the power (230V/50Hz) and connect the heater to the
power outlet. Neither fan nor the pump should become active
because the burner has not been switched on and the heat has
not been produced yet.
The heater should be placed away from combustible ma-
terials.
FITTING THE FLUE
To ensure the right combustion appropriate tting of the ue in
necessary. The following recommendations should be adhered
to when tting the ue:
Minimum ue diameter - 150mm.
Check tightness of joints between ue elements.
Minimum ue height- 5m.
The inside of the ue should be insulated (double skinned).
The tube should be in free air (the tip of the ue should be
above the rooftop).
If possible, all sections of the ue should be in vertical posi-
tion, horizontal positioning should be avoided, as well as bend-
ing of the ue. However, if it is necessary to bend a ue (for
example a ue bent in two places when it runs through a wall
or a window), the maximum angle is 45° with minimum height of
the ue increased to 6m.
CAUTION!
FLUES RUNNING THROUGH THE CEILING, WALLS
OR THE ROOF, MUST BE INSULATED IN ORDER TO
PREVENT FIRE. IT IS RECOMMENDED TO USE DOU-
BLE SKINNED FLUE IN PLACES WHERE THE FLUE
IS LIKELY TO BE TOUCHED BY THE GENERAL PUB-
LIC AND ON THE OUTSIDE OF THE BUILDING IN
ORDER TO GUARANTEE GOOD DRAUGHT AND PRE-
VENT CONDENSATION. NO MATERIALS SHOULD
BE PLACED CLOSE TO THE HEATER, EVEN INCOM-
BUSTIBLE ONES. FREE AIR MOVEMENT SHOULD
BE PROVIDED TO ASSURE PROPER COMBUSTION
PROCESS.

8. FUNCTIONNING
CONTROL PANEL
The control panel of universal oil heater is equipped with two
buttons (start, stop), potentiometer (min. 17kW, max. 33kW),
enabling the user to control the operation of the heater and the
diodes indicating the operating modes of the heater, equipped
with the alarm system in case of breakdown.

The device operates in the following modes:
STOP Device ready for use
HEATING UP Preliminary operating phase
IN OPERATION The device is working normally
SHUTTING OFF The device is shutting off
OVERHEATING Contingency switching off
VAPORISING PAN
OVERFLOW
Contingency switching off
The heat is produced during gas combustion when oil is
heated up to high temperature. When connecting the heater to
power network, the device is in stand-by mode (Stop). Heat is
not produced; niether fan, nor pump are working. At this time
the diode nr. 1 (power supply) on the control panel is glowing.
Pressing of the Start button triggers the diode nr. 2 (operation)
to turn on and the heater goes into the heating up mode. At this
time the diode nr. 2 (operation) is blinking. Once the burner is
heated up to 40°C the joints of thermostat placed next to com-
bustion chamber clutch activating the oil inlet pipe and blower
fan. The diode nr. 5 (pump) on the control panel goes on, blink-
ing for 30min, while the diode nr. 2 (operation) starts glowing
uninterruptedly, instead of blinking. At the beginning smaller
amount of oil is required, for at least 30 minutes after the fan
and the pump turn on, when the burner has not been heated up,
the device will work on lower power. During this time the pump
feeds the combustion chamber with approximately 1,46 kg/h of
oil. After 30 minutes of steady work the diode nr. 5 (pump) stops
blinking: at this point the power can be regulated with the help
of the potentiometer located on the front panel of the heater.
During the work on maximum power the chamber is supplied
with approximately 2,8 kg/h of oil.
The heater may switch off automatically if the combustion
chamber is overheated or in case of overow.
Overheating signal is generated by the bimetallic thermo-
stat located close to the fan. Opening of joints signals that the
threshold temperature has been exceeded. Control system
turns the pump off. Overheating is signalled by blinking of red
diode nr. 3 (overheating) on the control panel and the alarm. Fan
works until the temperature in the chamber falls below 35°C.
After the temperature in the chamber has fallen below 35°C, the
heater switches to the Stop mode.
Once the heater is in the Stop mode (and even after switch-
ing off and subsequently switching on the device) the overheat-
ing signal is on. This enables the user to nd out what caused
the heater to stop.
In order to reset the overheating signal and regain normal
functioning of the device, one should wait until the burner cools
off completely (the fan switches off) and press the button on
the casing of bimetallic thermostat. Then press the Stop button,
which will cause the overheating diode and the alarm go off.
Overow signal is generated by a mechanic sensor located
underneath the overow tank. Opening of joints signals that the
tank is overow. At the same time the pump is switched off. The
overow is signalled by the red diode nr. 4 (overow) blinking on
the control panel and the alarm. Fan works until the temperature
in the chamber falls below 35°C. After the temperature in the
chamber has fallen below 35°C, the burner switches to the Stop
mode. The overow tank is to be emptied, and then Stop button
should be pressed, which will cause the red overow diode to go
off. The heater may be switched on again.

HOW TO OPERATE THE DEVICE
Once engaged, the heater switches to desired modes de-
pending on settings chosen by the user and information trans-
mitted by sensors connected to the control panel.
If necessary, water may be poured from the tank and re-
placed with oil.
Make sure the oveow protection mechanism works properly
by pulling down the lever of the vaporising pan: it must turn back
to the initial position automatically, accompanied by the specic
„click” sound.
Make sure the oil inlet pipe (burner) is put in up to the stop
into the case of the heater (if not, put it in up to the stop).
Plug into the power socket (230V/50Hz).
Pull the upper part of the cover aside and take the burner
lid off, take the cylinder and the ring out (if necessary, clean
thoroughly the vaporising pan and its base, the burner, cylinder
and ring). Check if the vaporising pan is cool and clean, and
then pour approximately 250 ml of heating or diesel oil onto it.
Install ring and cylinder.
Put the burner lid back on, close the upper part of burner’s
casing.
Light oil using a piece of scrunched up paper that needs to
be put on re and thrown onto the vaporising pan.
Press Start button on the control panel (thе diode nr. 2 (op-
eration) will start blinking).
After approx. 10-15 minutes, depending on the temperature
in the room, the fuel pump will turn on. The heater starts working
on its minimum power 17 kW; 1,46 kg/h. After 30 minutes you
may regulate the heating power with the potentiometer. In case
the potentiometer was set in the position other than minimum
when turned on, in 30 minutes the heater will automatically start
working on the set power, according to the potentiometer set-
ting.
Each time Stop button is pressed followed by pressing the
Start button during operation will result in switching into the
Heating up mode of the burner.
SHUTTING OFF
Press Stop on the control panel, pump stops feeding fuel
onto the vaporising pan, and ventilation fan works only until the
burner has cooled off.
THE DEVICE MUST NOT BE UNPLUGGED FOR
AS LONG AS THE VENTILATION FAN IS WORKING,
THIS CAN BE DONE ONLY AFTER THE BURNER HAS
COOLED DOWN. THE BURNER SWITCHES OFF AU-
TOMATICALLY. PLEASE REMEMBER THAT AFTER
SWITCHING OFF THE DEVICE, THE CAST-IRON PAN
REMAINS HOTTER FOR LONGER (DEPENDING ON
THE TEMPERATURE IN THE ROOM) AND THE HEAT-
ER CANNOT BE RE-ENGAGED UNTIL IT COOLS
DOWN COMPLETELY.
MAINTENANCE
The burner requires various maintenance works. Following
producer’s recommendations regarding maintenance will as-
sure failure-free and safe functioning of the device.
Vaporising pan and elements of the combustion chamber
should be cleaned daily.
Check if the oil overow pipe is unobstructed (FIG5/p6), and
clean if necessary.
Clean the burner basin located inside the combustion cham-
ber at least once a week (burner basin is located under the va-
porising pan).
Check if air inlets in the lower and upper part of the combus-
tion chamber are not obstructed.
Clean the oil feed line once a week, maximum time of opera-
tion without cleaning the line feeding oil onto the vaporising pan
is approximately 7-14 hours (depending on the type of oil used
for heating).
Clean the fuel tank and oil pump lters during heating sea-
son.
If the heater is not used for a longer period of time, the com-
bustion chamber and the tank should be cleaned thoroughly,
and then covered with a thin layer of oil in order to prevent cor-
rosion.
IT IS RECOMMENDED TO HAVE ALL MAINTE-
NANCE WORKS DONE EACH SEAZON BY AN AU-
THORISED DEALER.
